Below is a list of the regular CBS TV shows and their 2010-11 season average ratings to date. It only incorporates the ratings for original episodes and not repeats. The data is sorted by the all-important 18-49 demographic averages. The closer a show is to the bottom, the more likely it is to be cancelled. Fridays and Saturdays are the least-watched nights of TV so those shows get lower numbers.
